The primary object of this invention is to manhole having a liquid-sealed cover. Ma- 55 provide an improved method and process of terials may be introduced to the initial comdisposing of waste materials suchas sewage, partment by a pipe having a trap to pre night, soil and garbage, in such manner that vent the escape of gases.

This tank preferably is This rocess of disposing of sewage, night divided by a transverse partition of soft soil and garbage will be advantageous for brick or other substantially porous substance school buildings, hotels, public or private and the waste materials are deposited in the buildings of any character, camps and the initial compartment, some of the liquid porlike, and provides a sanitary and economical tions passing through the partition to the method of ettin rid of these materials and other compartment, while the solids are rerendering t em t to be utilized for useful tained inthe initialcompartment.

I claim as my invention- 1. A process for dis osing of sewage, night soil, garbage and t 1e like, which consists in introducing such materials into -a closed and sealed tank having a substantially porous partition through which the liquid portions may pass, permitting the solid and liquid portions to remain in said tank for a considerable time whilenitrate-producing bacteria act thereon and therein, and utilizing some of the liquid portions from time to time for'flushing the entrance of new material to the tank.

' uid portio 2. A process for disposing of sewage, night soil, garbage and the like, which consists in introducing such materials into a closed and sealed tank having a porous partition through which the liquid portions only may pass,-permittiug the solid and liqv lisiito remain in said tank for a considerable time while nitrate-producing bacteria act thereon and therein, and introducing a, germicidal substance into said tank for the purpose of killing dangerous germs and the like.
